Profile 3mm lower - Suspension as mentioned
Front bumper with additional lower section - This is a splitter and is held on with 4 bolts or something does nothing for performance.
Enlarged rear spoiler above hatch - Not really needed purely cosmetic.
Greater downforce - Probably generated by the above but not nessecary really
Revised suspension - That goes with number 1
Higher front spring rates - That goes with Number 1
Front track 20mm wider - That goes with Number 1
New wheel rim offset - That goes with number 1 as well as its the increased tracking meaning the offset has changed but again is easily added to the FF if wanted.
Overall weight reduced by 89kg - Through the loss of the seats, Xenon Headlights, ABS Ancilleries, Lighter Alloys - But again for .2 of a second increase in acceleration would rather keep the luxuries.
Spare wheel removed (replaced by 2 anti-puncture inflators) - Not really any use whatsoever if you get a puncture though as I'm sure omar would agree, and tbh I feel better knowing I have a spare
Air conditioning removed - Goes with Weight Loss
Side airbags removed - Goes with Weight Loss - But that isn't anything to be happy about :clown:
Xenon headlamps removed - Weight Loss
Sound deadening adapted - Prefer a quite car, The FF sounds meaty enough on accerlation even with the Sound deadening - Wieght Loss again.
Braking system redesigned without ABS - Braking system shagged due to renault forgetting to use bias valves. :clown:
Front castor angle increased by 3° - Number 1
Rear track 10mm wider - Number 1
16"x7" Speedline 'Turini' alloy wheels - Got a good point.
Not knocking the Cups I would use one for tracking it, But I did have the choice of the FF and the Cup and chose the FF purely for the extras over the cup. You also missed off that the Cup doesn't have traction control and ESP something that has already been useful on mine, Especially on motorways with heavy wind :evil:
The Cup is a lower spec FF marketed by Renault as an enthusiasts car. But its still a damn good car with it. So don't take the above as offence just an opinion.
